An article in the current issue of Global Change Biology Bioenergy examines the carbon sequestration potential of Miscanthus plantations on commercial farms. Researchers evaluated Miscanthus plantations in Ireland, where planting has been subsidized by the government. Carbon sequestration is expected to vary among different farming practices and soil characteristics. They found significant soil carbon sequestration under Miscanthus on both former tilled land and former grasslands after...

A new study shows that as climate change enhances tree growth in tropical forests, the resulting increase in litterfall could stimulate soil micro-organisms leading to a release of stored soil carbon. The research was led by scientists from the Centre for Ecology & Hydrology and the University of Cambridge, UK. The results are published online August 14, 2011 in the scientific journal Nature Climate Change. The researchers used results from a six-year experiment in a rainforest at the...

Breeding crops with roots a metre deeper in the ground could lower atmospheric CO2 levels dramatically, with significant environmental benefits, according to research by a leading University of Manchester scientist. Writing in the journal Annals of Botany, Professor Douglas Kell argues that developing crops that produce roots more deeply in the ground could harvest more carbon from the air, and make crops more drought resistant, while dramatically reducing carbon levels. In principle, any...

Scientists say a tundra fire in the circumpolar arctic released about as much carbon into the atmosphere as the tundra has stored in the previous 50 years. The study, published in the July 28 issue of Nature, of the Anaktuvuk River fire on Alaska's North Slope revealed just how quick a single tundra fire can offset or reverse a half-century worth of soil-stored carbon. "Fire has been largely absent from tundra for the past 11,000 or so years, but the frequency of tundra fires is increasing,...

Turning back the climatic clock in Australia Improving land management and farming practices in Australia could have an effect on global climate change, according to a study published in the International Journal of Water. Natural Sequence Farming is a descriptor used when sustainable agriculture mimics the once highly efficient functions of the Australian landscape. NSF pioneer Peter Andrews of Denman in New South Wales and coordinator of the NSF movement, Duane Norris of Hardy's Bay, New...

Web-based tool helps farmers reduce greenhouse gas losses and gain economic advantage Greenhouse gas markets, where invisible gases are traded, must seem like black boxes to most people. Farmers can make money on these markets, such as the Chicago Climate Exchange, by installing methane capture technologies in animal-based systems, no-till farming, establishing grasslands, and planting trees. Farmers, students, extension educators, offset aggregators, and other stakeholders need to understand...

Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in the March 24 issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which is about 10-15 percent higher than previous measurements. That number -- about 98 petagrams of...

Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories. ORNL and LANL scientists are exploring the large potential of the earth's soils to sequester carbon, with estimates claiming that new land-use practices could greatly reduce U.S. carbon emissions by as much as 25 percent. But exactly which practices...

A recent study has confirmed that although there was a large reduction of organic carbon and total nitrogen pools when prairies were first cultivated and drained, there has been no consistent pattern in these organic matter pools during the period of synthetic fertilizer use, that is, from 1957-2002."For these prairie soils, some of the best in the world, declines in organic matter from cultivation were likely completed by the 1950s, and since then organic matter pools have remained...

Methods proven worldwide can sustain farmer profits, address hunger and malnutrition and restore ecological health KUTZTOWN, Pa., Dec. 9 /PRNewswire-USNewswire/ -- To best feed the world, a growing number of researchers, development experts, farming groups and environmentalists are calling for new emphasis on sustainable agricultural practices that make a sharp break from current policies. A newly released Rodale Institute research paper reviewing replicated research shows that the latest...
